The DNS (Domain Name System) cache is responsible for storing past DNS lookup requests. It helps to speed up future DNS queries by providing a faster response as there is no need to send fresh requests to DNS servers. However, in certain situations, it may be necessary to flush the DNS cache on your Windows 11 computer. This may include situations such as troubleshooting network issues or updating DNS records. Here are some ways to flush the DNS cache on Windows 11:

1. Using Command Prompt:

The command prompt is a built-in tool on Windows 11 that allows you to execute commands. To flush the DNS cache using the command prompt, follow these steps:

Step 1: Open the command prompt by typing “cmd” in the search bar.

Step 2: Right-click on the command prompt icon and select “Run as administrator.”

Step 3: Type the following command in the command prompt window and press Enter: ipconfig /flushdns.

Step 4: The DNS cache will now be flushed, and you should see the message “Successfully flushed the DNS Resolver Cache.”

2. Flushing the DNS Cache through Windows PowerShell:

PowerShell is another command-line tool in Windows 11 that can be used to execute commands. To flush the DNS cache using Windows PowerShell, follow these steps:

Step 1: Open Windows PowerShell as an administrator.

Step 2: Type the following command in the PowerShell window and press Enter: Clear-DnsClientCache.

Step 3: The DNS cache will now be cleared, and you should see the message “DNS client cache successfully cleared.”

3. Using Windows Network Troubleshooter:

Windows 11 has a built-in troubleshooter tool that can help to fix some network issues. One of its features is clearing the DNS cache. To clear the DNS cache using the network troubleshooter, follow these steps:
